OCTAHYDROFLUORENYL METAL COMPLEXES, SUCH AS OCTAHYDROFLUORENYLTITANIUMTRICHLORIDE, OR RING-SUBSTITUTED OCTAHYDROFLUORENYL METAL COMPLEXES WHEREIN THE METAL IS IN THE +2, +3 OR +4 FORMAL OXIDATION STATE ARE PREPARED BY REDUCTION OF TETRA- OR HEXAHYDROFLUORENYL METAL COMPLEXES. THE REDUCTION REACTION MAY BE CARRIED OUT AT AMBIENT PRESSURE AND TEMPERATURE IN THE PRESENCE OF A CATALYST. THE PROCESS OF THE PRESENT INVENTION PERMITS PREPARATION OF OCTAHYDROFLUORENYLTITANIUM METAL COMPLEXES FROM A SERIES OF HIGH YIELD REACTIONS STARTING WITH FLUORENE. THE RESULTING COMPLEXES ARE USEFUL AS CATALYSTS IN PREPARING POLYMERS HAVING A SYNDIOTACTIC STEREOSTRUCTURE.
